SPECIFICATION forming part of Letters Patent No. 392.343, dated November 6, 1888.

Application filed April 19, 1888. Serial No. 271,185. (No model.)

.To aZZ whom it may concern:

Be it known that I, LEVI JUDGE, a citizen of the United States, residing at Olean, in the county of Cattaraugus and State of New York, have invented a new and useful Improvement in Wood-Working Machines, of which the following is a specication.

My invention relates to an improvement in wook-working machines for beading and grooving the stiles of doors, sashes, and blinds; and it consists in the peculiar construction and combination of devices that will be more fully set forth hereinafter, and particularly pointed out in the claims.

In the accompanying drawings, Figure lis an elevation of the front side of a wood-working machine embodying my improvements. Fig. 2 is a top plan view of the same. Fig. 3 is a vertical longitudinal sectional view taken on the line :t x of Fig. 2. Fig. 4. is a similar view taken on the line y y of Fig. 2. Fig. 5 is a vertical transverse sectional view taken on the line z e of Fig. 2. Fig. 6 is a similar view taken on the line w w of Fig. 2. Fig. 7 is a detailed perspective view of the movable cutter-head. Fig. Sis a similar'view of the cutter-head for beading the stiles. Fig. 9 is a detail view.

A B represent the sides of the frame. The side A is provided on its inner side, at a suitable distance from its front end, with a vertical groove, C. On the inner side of side B, and in line with groove C, is secured a guideway, D, which is provided on its inner side with a vertical groove, E. The sides of the guideway project beyond the central grooved portion thereof and form anges F, which are screwed or bolted to the side B, as shown.

G represents a vertically-movable head, which is provided on opposite sides with vertical tongues that fit in the grooves C and E, and thereby enable the said head to be raised or lowered in the frame.

the direction ofits length toward or from the proximate side A of the frame.

M represents a horizontal shaft, which is journaled in the bearings K, and is provided near its center with a pulley, N. One end of the said shaft projects beyond the side A of the frame and is reduced to form a spindle, 0. At the inner end of the said spindle is a collar or flange, l?.

R represents a pair of circular heads, which are slipped on the spindle, are provided on their opposing sides with tangential grooves S, and in the said grooves are secured cutter-bits T, the outer ends of which are provided with chisel-edges, and are adapted to cut grooves in the stiles for glass or panels.

U represents a washer, which is slipped on the spindle andbears against the outer head, R, and V represents a nut which is screwed on the threaded outer end of the spindle and serves to clamp the cutter-bits firmly in position between the heads.

In the lower end ofthe head Gisjournaled a shaft, W, which is provided with a large pulley, X, and a small pulley, Y, said pulleys being keyed to the said shaft. An endless belt, Z, connects the pulley X with the pulley N, and is thereby adaptedv to impart rotary motion to the shaft M and to the cutters T.

A represents a large pulley, which is journaled on a spindle that projects outward from the side B in line with the shaft M. Itigidly secured to the inner side of this pulley, or formed integrally therewith, as may be preferred, is a pinion, B.

C D represent a pair of feed-shafts, which are journaled in bearings on the upper side of the frame and are arranged on opposite sides of the shaft M. The said shafts are vertically movable in their bearings, and the bearings of the shaft D are longitudinally adjustable on the upper side of the frame, the latter being provided with longitudinal slots E to receive the bolts of the bearings, so as to permit the longitudinal movement of the latter, as will be readily understood. To one end of the shaft D is keyed a spur-wheel, F, which meshes withv the pinion B', and to the similar end of the shaft C is keyed a spur-wheel, G', which also meshes with the pinion B', said wheels F IOO and G being out of engagement with cach other. The opposite ends of said shafts C and D are provided, respectively, with longitudinally-grooved feed-rollers ll. l.

K represents a rockshaft, which is journaled in the sides A B near the lower front corners ofthe same, is provided with an operating-lever, L', which extends upward therefrom, and has a pair ol' rock-arms, M', which extend rearward therefrom and have their free ends loosely connected to the lower sides of the vertically-movablehead G. By means of this arrangement of devices the head (l, carrying the cutters T, may be raised or lowered by moving the lever L', as will be readily understood.

N represents a bar, which is arranged on the inner side ofthe side A, has its rear end pivoted thereto, and has its projecting front end free to move vertically and provided with a weight, O', which is longitudinally adjustable thereou. Link-rods F connect the said weighted bar to the outer ends of the rollershafts C D', and thereby the feed-rollers may be raised by moving said weighted bar upward, and the gravity of the latter keeps the said feed-rollers normally in coutactwith the stile or other obiect on which the machine is operated, as will be readily understood.

R' represents a curved bracket-arm, which projects outward from the side B of the frame and forms the bearing for one end of a shaft, S', the opposite end of said shaft being journaled in the bearing in the side B. A pulley, T', is rigidly secured to the shaft S, and a. cone-pulley, U', is also secured to the said shaft.

V represents an endless belt, which connects the pulleys T and A.

\Vrepresents a lever,which is fulerumed on the side B of t-he machine, and is provided with a pulley, X, which is adapted to bear against the endless belt V. Said lever and said pulley form a belt-tightener, which is adapted to be operated so as to cause the belt V to create any desired friction on the pulleys A and T.

Y represents a pair of longitlulinally-adjustable standards, which are secured to the tloor or other suitable support at a suitable distance beyond the rear end of the frame. In bearings with which the said standards are provided is j ournaled a eounter-shaft,Z. Said shaft has a fast pulley, A2, a loose pulley, B2, a large pulley, C2, a smaller pulley, D2, and a cone-pulley, The latter is connected to the cone-pulley U by means of an endless belt, F2. The pulley D2 is connected to the pulley Y by means of an endless belt, G, andan endless belt (not shown) operated by an engine or other suitable motor is adapted to pass around the fast pulley A and to be shifted from the same onto the loose pulley B2, so as to rotate the counter-shaft, and thereby actuate the machinery or to throw the said countershaft and machinery out of gear.

H2 represents a transverse bar, to the ends of which are connected a pair of bearingblocks, l?. Said bar and said bearing-blocks are arranged on the upper side of the frame at a suitable distance in rear of the rollershaft G, and are provided with slots K,whieh are arranged transversely on the upper side of the frame. Screws or bolts L extend through the said slots and engage the upper side of the frame and adapt the bearings l2 to be adjusted laterally ou the same and clamped at any desired adjustment, as will be readily understood.

Mi represents a shaft,which isjournaled iu the bearings l2, is provided with the rigid pulley N2, and has one end projecting beyond the side A of the frame and provided with a eutter-head, O2. The said cutter-head is provided at its corners with concave grooves P2, that extend in the direction of its length, and on opposite sides of the said cutter-head are secured suitable planing, beveling, grooviug, or tonguing knives or cutters, R2.

SIl represents au endless belt, which connects the pulleys C2 and N".

From the foregoing description it will be understood that the motion of the countershaft may be communicated to the shafts M2, M, C', and D at the will of the operator, so as to cause the said shafts M and M to rotate at a high rate of speed and the rollershafts C and D' to rotate at a slow rate of speed.

T represents a fender, which is secured to the upper side of the frame and is arranged over the cutters T, and is adapted to prevent the dust and shavings'made by the said cutter from ilying into the face ofthe opel'ator.

U'L represents a standard or knee, which is arranged on the upper side of the frame in rear of the shaft M2, and is provided with longitudinal vertical slots V, through which extend bolts or screws V?, that enter the upper side ofthe frame, and thereby adapt the knee or standard to be moved longitudinally on the frame and secured at any desired adjustment.

X2 represents a curved shield,whicl1 is provided with a curved arm, Y?, that is pi voted to one side of the standard or knee U". The latter has a stop-pin, Z2, projecting from the outer side thereof, to support the shield when the latter is turned upward from over the cutter O, and the said shield is provided with a projecting pivoted arm, A, which is provided with an adjustable weight, B", the function of the said weight being to cause the free side of the shield to bear upon the upper side of the stile with any desired pressure.

Cf represents the feed-table, which is provided at its inner side with a depending longitudinal flange, D. From the inner side of this ilangc projects a trunnion, E, which enters the vertical slot F in the side A and is adapted to move upward and downward therein. A stud, G", is journalcd in an opening in the Ilange D" and has its projecting ends squared and adapted to work in a vertical groove, H, in the side A. Avertical screw, I3, extends downward through an opening in the ICO IlO

IZO

side A above the slot F3, and said screw engages the threaded opening i'n the trunnion E.

K3 represents a pair of setscrews,which engage threaded openings in the iiange D3 and are adapted to impinge against the side A, so as to secure the feed-table at any desired vertical adjustment. The slot F3 and groove H3 serve as guides for the feed table, and the screw l3 serves to support the feed-table and to adjust the same.

L3 represents a series of pins, which project from the upper side of the feedtable,near the outer edge thereof, are secured in openings in the feed-table by'means of set-screwsM3,and are provided with springs N3, which are adapted to bear against the outer side of the stile a on which the machine is operated, so as to keep the said stile in contact with the side A of the machine and enable the same to be directed ina straight line thereon.

In order to bead and groove a stile which has previously been mortised, the stile is engaged by the feed-roller and is moved by the rotary motion ofthe said roller, so as to carry the stile past and under the cutter-heads, the lever W being turned so as to cause the pulley X to tighten the belt V and enable the latter to operate on the pulley U, thereby and thereby cause the same to eut a groove therein. I

When the stile is urged forward on the feedtable by the feed-rollers after the. revolving cutters have been raised from the mortise, the cutters attached to thecutter-head O2 serve to bevel, groove, bead, or cut tongues upon the stile, as may be desired, according to the shape ofthe cutters.

A wood-working machine thus constructed is adapted not only to operate on the stiles of windows, doors, and bli'nds,but may be employed for a great variety of other articles manufactured of wood. l By reason of the feed-table being vertically adjustable on the side A of the frame the machine is adapted for working wood of various sizes.

Having thus described my invention, I claim- 1. The combination of the frame, the head G, vertically movable in said frame, the plate H, movable laterally on the upper side of the head, the shaft journaled in the lowerv end of the head, movable vertically therewith, and having the pulleys X Y, the shaft M, journaled in bearings in the plate Il and having the pulley N, the cutters adapted to be connected to the projecting end of the shaft, the endless belt connecting the pulleys X N, one end of said shaft projecting beyond one side of the frame, andthe counter-shaft having the pulley D2 and the endless belt connecting said pulley with the pulley Y, substantially as dcscribed.

2. The combination of the vertically-movable head, the plate H, movable laterally on the upper side of the head and having the bearings, and the revoluble shaft M, jour- ;naled in said bearings and adapted for the attachment of the cutters, substantially as described.
